RSV – anti-condensation heaters for electromotors

Electromotors become hot during operation and then cool down after being turned off. If the environment is humid, this humidity will condensate in the motor. A short-circuit can then occur after turning it on again. To avoid the condensation it is necessary to keep the motor temperature a few degrees above the ambient temperature.

RSV – anti-condensation heaters for electromotors

Especially designed for the electric motor producers, the RSV series of heating belts prevents the humidity condensation in electric motors.

The factory version and fiberglass protection enable the belts to be varnished or impregnated with the stator. Ensuring a solid heat contact with the winding and a maximal heat transfer, makes the RSV belt not only convenient but also higly efficient in supressing humidity condensation. Usually, the RSV heaters turn on when the machine is switched off.
